hmm, I have a question about the "lore" consistency !
there's this scene at Luke's apartment where Tina and Tanya hears the footsteps of someone approaching, i know that someone is Julia.
the strange thing is this scene is directly followed by the labs scene which's happening at the same time as the apartment one, according to the game. then Julia appears again!
it won't be as strange if the pre-screen said "earlier" rather than "meanwhile".

Please let me know also if you manage to get all the endings - an easy way to test the Mars only storyline is to fail the first boss fight. While to test Earth only fail Tom vs Sarah boss fight (is the first scene where you can end Mars storyline).
Next thursday is my birthday and finally getting this game out of beta would be a great present

That shouldn't happen, but Elmsdor had that problem too, so I added an extra check, usually happens when:

Spoiler:

Luke accepts Sarah's offer AND Tom and Helen are lovers.
That case wasn't included, so now I've added it to the Protector ending.

if your case is different, would be cool if you can send me the savegame before it ends (you can rollback from the credits and save).
So far with Elmsdor help we were able to get all the endings except Earth Sweet Earth - if anyone managed to get it let me know! it seems either VERY HARD or perhaps impossible (if is impossible I mean I made a mistake while checking some variables).

I think will leave the possibility to play in both modes even in the final game, so everyone can experience the game how they want.

yeah sure.
shall I pm it here or via email ..?
my case was a bit different as I didn't accept Sarah's offer.

Spoiler:

instead Luke asked for the help of both Tom and Helen to hack Sarah's account and destroy the virus.
not sure if Tom and Helen are lovers, although Luke did admit that he does not love Helen anymore !!
Tanya won the battle against Julia, chose Lucas' brain who betrayed her, then was captured .
Tina was brain-extracted and Rob was killed !
Jason was in good relationship with Tanya !

It seems that in all your playthrough Tom and Helen aren't lovers or die, in this case you can't get to the Moon. If you follow the walkthrough instructions, it works (some paths are much harder). I know Elmsdor followed the walkthrough and was able to get all the endings except Earth Sweet Earth because is bugged (will fix it as soon as I get the file from Aveline to check his save).
About the sadness, is not like the first game was particularly happy either (apart a few endings).
